DISCUSSION: As deep convection developed in the vicinity of the Gulf Coast region yesterday afternoon and evening, a very impressive convective structure known as a mesoscale convective complex (MCC) blossomed fairly quickly as seen in the brief visible/infrared satellite imagery loops below as well as the lightning analysis overlay during parts of this brief animated clip! Note how towards the beginning of this MCC's growth stage(s) you can identify the regions of deepest convective growth and expansion by way of the "bubbling" appearance on visible satellite towards the western portions of this impressive MCC. You can also denote the presence of what are referred to as "gravity waves" which are essentially a mechanism by which higher areas of momentum are transferred between the lower and upper portions of the atmosphere and tend to oscillate and they form and move downwind (or to the east) in the Northern Hemisphere!
